Recent optimizations to fork() introduced a regression, that could cause the subprocess to fail unexpectedly, when TlsAlloc() returns a different index. This is because we were burning the indexes into the displacement of x86 opcodes. So when fork() happened and the executable memory copied it would use the old index. Right now the way this is being solved is to not copy the executable on fork() and then re-apply code changes. If you need to be able to preserve self-modified code on fork, reach out and we can implement a better solution for you. This gets us unblocked quickly.
